The new LUMIX G VARIO 100-300mm / F4.0-5.6 / MEGA O.I.S. is comprised of the lens unit with 17 elements in 12 groups including an ED lens. Adopting the ED lens in the first lens group, the chromatic aberration is effectively suppressed to render sharp, high contrast images with stable optical performance over the entire zoom range. The integration of stepping motor with exclusive zoom tracking control system and inner focus drive system realizes the use of accurate and high speed contrast AF, yet keeping its sound of action as silent as possible.

Rated 5 out of 5 by Lee Great Lens!
I use this lens on an Olympus body and it works great. I love the image stabilization OIS (I set my camera to use the len's stabilization first). I can handhold fully zoomed in and get sharp images even in less than ideal conditions. Auto-focus is fast considering the length and range of the lens.
The most important feature is the outstanding image quality. I received the lens on a Friday and took it to an NFL training camp on Saturday. I started out with some blurry shots, but my technique improved and I was soon getting 4 out of 5 snaps. The color and rendering are excellent! I would choose this lens again without hesitation.

I love this lense with my small GH2.
But hey Panasonic, how about a 200mm-400mm? Or larger.
Anyone else agree let Panasonic know we like the telephotos.

Rated 5 out of 5 by PhotoBen19 Fantastic Zoom
I received this zoom lens as a gift and could not be happier! I purchased the Lumix G3 last year and up until I received this lens I have been using the kit lens. I must say that this lens is sharper throughout the entire zoom range and auto focus is fast. I would definitely recommend this to anyone looking for a fantastic zoom lens!

Rated 2 out of 5 by Ed Poor zoom performance
Picture quality, overall performance and price good but zoom performance bad. Zoom ring is so stiff and so much pressure must be exerted to rotate the zoom ring that there is no way to zoom in or out while filming.
Problems: Slow zooming is jerky and destabilizes image.
